BUTTON AND STUD.

SPECIFICATION forming part of Letters Patent No. 235,634, dated December 21, 1880.

Application filed June 26, 1880.

To all whom it may concern Be it known that I, J onN KENNEDY, of Attleborough, county of Bristol, and State of Massachusetts, `have invented a new and useful Improvement in Buttons or Studs, of which the following description, in connection with the accompanying drawings, is a specification.

My invention relates to a separable button or stud for garments, and has for its object to produce a` button of neater appearance and more convenient and certain operation than the separable buttons now in common use.

The shank of one portion of the button is made to slide longitudinally within the exterior or tubular shank ofthe other portion, and is provided with a catch projecting from its side, which, when the said shank is inserted in the corresponding tubular shank to unite the two portionsof thebutton,as wheuin thebuttonhole, engages an annular groove Within the said tubular shank and prevents the inserted shank The said annular groove does not extend Wholly around the inside of the said exterior shank, but is iilled up for a portion ot' its length, so that after the two portions of the button have been fastened together by the engagement of the said catch in the said groove, the said catch may be disengaged to permit the separation and removal of the button by rotating one portion of the button and its connected shank upon or within the other portion until the blank or illed-up part of the groove comes opposite the said catch, pushing it aside and allowing its connected shank to be withdrawn from the tubular shank of the other portion of the button surrounding it.

Figure 1 is a sectional View of a separable button constructed in accordance with my invention, the two portions of the button being fastened together as when in use. Fig. 2 is a transverse section thereof on line x Fig. l; and Fig. 3, an elevation, partly in section, of one portion of the button detached.

rEhe main portion a. of the button is connected with a shank, b, (shown as cylindrical in shape,) and provided with a longitudinal slot, c, extending along one side thereof. Withinthe said shank b is the catch d, (shown as a wire,) secured at one end to the outer end of the shank b by soldering or other suitable means, the said wire extending longitudi- (No model.) l

nally through the said shank to a point near the junction of the said shank with the base portion a of the button, where its end 2 projects laterally through the slot c outside of the cylindrical surface of the shank b. The other portion, c, of the said button is provided with a tubular shank, f, of suitable size to pass over and slide longitudinally on the shank b of the other portion, a, of the button, the end `of shank f, when passing over the projecting end 2 of the catch d, causing it to yield and be pressed through the slot c wholly inside the shank b until, when the said shank b has passed for its entire length within the tubular shank j', the annular slot 3 in the said'tubular shank comes opposite the end 2 of the catch d, which, byits elasticity, springsfw out through the slot d and engages the groove 3, as shown in Fig. 1, to fasten the two portions of the button together. The groove 3 does not extend wholly around the inside of the tubular Shank f, but terminates in a blank portion, 4, employed to disengage the catch d When the said blank portion 4 is opposite the end 2 of the said catch.

When desired to disen gage the two portions of the button, one portion, as a., thereof, with Vits connected shank Z), is rotated or turned Within the other portion, c, and its connected shankj until the end 2 of the catch d comes to the blank portion 4 in the groove 3, and is in the further rotation forced thereby back within the shank b, so that the said shank can now be freely withdrawn from the tubular shank j'.

I claim- 1. In aA separable button or stud, a shank connected with one portion of the button and provided with a projecting catch, a tubular shank connected with the other portion of the said button and adapted to slide longitudinally over the other shank and catch, the said tubular shank being provided With a groove to be lengaged by the said catch to hold the two portions of the button together, and the said groove having a blank portion to disengage the said catch and allow the portions of the button to be detached, substantially as described.

2. In a separable button, the internal shank and spring-catch projecting therefrom, combined with the external shank, provided with IOO an internal groove to be engaged by the said catch, kthe said groove not extending Wholly around the said external shank, to enable the operator7 by turning the said shank, to bring its blank or ungrooved portion opposite the catch, to disen gage the said catch and separate the two portions of the button, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two sub- 1o soribin g Witnesses.
